I recently did the osmosis potato experiment, where you cut strips of potato and leave them in different concentrations of sucrose solution overnight then you work out the change in mass, and the percentage change in mass i need three limitations, and ways to overcome them, the one i already have is the. The input variable will be the concentration of the solution the 100% solution is sodium chloride dissolved in water (salt water) this will be referred to as the 100 % solution from now on but the type of solution is not important as osmosis is all about differences in concentrations [tags: gcse biology osmosis coursework].
